Abstract : This poster presents ongoing research on automatic generation and execution of embedded parallel C code. We target safety-critical avionics programs specified in the synchronous language Lustre. The work described is part of the ITEA 3 project ASSUME (September 2015 - August 2018). ASSUME focuses mainly on embedded software engineering for multi-/many-core platforms. Both synthesis, e.g., automatic code generation, and verification, e.g., static analysis, of programs are addressed in the project. ASSUME is driven by the use cases of its industrial partners. One of these use cases consists in the parallelization of an avionics application comprising about 5500 Lustre nodes. After an overview of the ASSUME project, both parallel code generation and execution on a many-core platform will be presented and demonstrated.
